An estimated 10 million families, individuals, trusts, and estates own 39 percent of the forestland in the United States, excluding interior Alaska. Using segmented regression, the relationships between size of forest holdings and the attitudes and behaviors of these family forest ownerships were tested using data from the 2018 iteration of the USDA Forest Service’s National Woodland Owner Survey. All 16 variables tested have significant relationships with size of forest holdings, and 13 have one or more breakpoints, ranging from 40 to 5,854 ac, where the relationships between the variables change. Timber as a reason for owning, timber harvesting activities, management plan, advice received, land certified, tax program participation, cost share, recreation, land tenure, recreation, taxes and heirs as concerns, land transfer, and income from forestland have positive relationships with size of forest holdings; resident ownership has a negative relationship; and wildlife as a reason for owning and owner age have mixed relationships.

一种规模并不适合所有人：家庭森林控股规模与所有者态度和行为之间的关系

估计有 1000 万个家庭、个人、信托机构和庄园拥有美国 39% 的林地，不包括阿拉斯加内陆地区。使用分段回归，使用美国农业部林务局国家林地所有者调查的 2018 年迭代数据测试了森林拥有量与这些家庭森林所有权的态度和行为之间的关系。测试的所有 16 个变量都与林地规模有显着关系，13 个有一个或多个断点，范围从 40 到 5,854 ac，变量之间的关系发生变化。木材作为拥有的原因，木材采伐活动，管理计划，收到的建议，土地认证，税收计划参与，成本分摊，娱乐，土地使用权，娱乐，税收和继承人关注，土地转让，林地收入和林地收入与林地规模呈正相关；居民所有权负相关；和野生动物作为拥有和拥有者年龄的原因有着复杂的关系。
